The Radon transform and its adjoint, the back-projection operator, can both be expressed as convolutions in log-polar coordinates. Hence, fast algorithms for the application of these operators can be constructed by using FFT, if data is resampled at log-polar coordinates. Radon data is typically measured on an equally spaced grid in polar coordinates, and reconstructions are represented (as images

Diesel engines are the most common engine technology used in transportation. Its widespread use comes from its inherent high efficiency and its relative low cost. It suffers from pollutant emission issues, however, that need detailed understanding of their origins to meet the strictest current and upcoming emission standards. The work presented in this thesis focuses on the study of the mechanism

There is an ongoing trend towards higher automation level in process control systems. The purpose of a plant is to manufacture some product at a high production rate with a consistent quality, while minimizing the use of resources in terms of energy consumption, raw material and labor. With a higher degree of autonomy in the control system, it is possible to improve all these aspects, thus increas

This thesis has been taking a starting point from a micro-level that focuses social structures, ethnic segregation and processes of development as phenomena from different levels of perspectives. The research focuses on housing-conditions in the urban room and take a starting-point in 1992 when an increased number of immigrant households, depending on social welfare, moved into Herrgården (Manor-H

Thesis purpose: The purpose of this study was to gain an understanding of consumers' perceptions of the phenomenon of brand activism, and how they respond to it. Theoretical perspective: For the theoretical foundation we drew upon the literature streams within brand activism, consumer activism and brand meaning. Based on these three literature streams we identified relevant key concepts and c

This thesis investigates the social position and political agency of women excombatants of the Farc-EP who laid down their arms after the 2016 peace agreement between the Colombian government and the Farc-EP. I show how, through the laying down of arms and reincorporation, women ex-combatants come to occupy a specific social position under historical and global power relations and intersecting for

This thesis is about the copyright protection for single dance moves. The purpose of this thesis is to come to a conclusion as to whether single dance moves could be protected by copyright in Europe and if it should be protected. These questions originate from the United State lawsuits against the gaming company Epic Games and their use and sales of allegedly copyright protected dances. The firs

Den svenska rättsstaten står inför allvarliga prövningar. Det grova våldet till följd av skjutvapen har ökat markant i Sverige, och risken för tredje man att drabbad av skjutningar och detonationer på offentlig plats har ökat. Samtidigt som våldet även blivit mer hänsynslöst och likgiltigt. Antalet brott inom denna kategori ökar, men uppklaringsandelen är låg. En förklaring till den dystra statistThe Swedish rule of law is facing serious challenges. The use of firearms resulting in severe injury has increased significantly in Sweden, and the risk of third parties being affected by shootings and detonations in public places has increased. At the same time, the violence has become more ruthless and indifferent. While this type of violence is increasing, law enforcement agencies are at a loss

European environmental policy has in the recent years become more and more prominent, and with the European Commission launching the European green deal, environmental policy has become a part of the centre stage of European policy. When looking to decarbonise the economy natural gas becomes a favourable solution. However, natural gas is not without a problem i.e., natural gas is still a fossil f

The copolymer of N-isopropylacrylamide (NIPAM) and methacryloyl derivative of spirobenzopyran (MSBP) with a molecular weight of 21 000 g/mol and the average molar MSBP content of 1.9% was prepared by free radical polymerization. The copolymer displayed its phase transition in water in the temperature range of 30-50 degreesC. UV irradiation of its aqueous solution caused photoinduced transformation

This thesis presents a number of results and algorithms for the numerical solution of problems in geometric computer vision. In geometric computer vision one tries to extract geometric information about the world and the observer from a sequence of images. Estimation of scene structure and camera motion using only image data has been one of the central themes of research in photogrammetry, geodesy

The aim of the present work is to describe the semantics and the discursive functions from a general cognitivist point of view of the usage of the Present Perfect in the spoken Spanish of Chile, Paraguay and Uruguay. It is argued that cross-linguistic values that prevailing theories often ascribe to perfect, such as continuity, current relevance and recency to the speech time –ST– do not offer a c

The human side of mergers and acquisitions (M&A) – with focus particularly on resistance - has puzzled scholars for decades. Still, there is little discussion as regards to how the concept should be defined or understood. Often expressions of resistance, rather than its actual content, are described. What do personnel actually oppose? In this dissertation, the content, process, and context of

Popular Abstract in Swedish I och med att mjukvarubaserade produkter ökar i antal ökar också vikten av en effektiv mjukvaruutvecklingsprocess, ur ett konkurrensperspektiv. Bristfällig produktkvalitet och höga utvecklingskostnader är något som mjukvaruutvecklingsorganisationer under många år har kämpat med. Studier inom SPI (software process improvement) syftar till att förbättra produktkvalitet ocThe number of software-based products is increasing, which is why the importance of an efficient software development process is also increasing, from a competitive advantage perspective. For years, software development organizations have been plagued by poor product quality and high development costs. Studies in software process improvement (SPI) have concerned themselves with improving the softw

Riskkapitalmarknaden kan härledas så långt tillbaka som till 1940-talet då de första private equity-investeringarna genomfördes i USA, och sedan dess har branschens utsträckning ständigt förändrats i takt med det rådande ekonomiska klimatet, både hög- och lågkonjunkturer, och är idag ett starkt etablerat fenomen även i Sverige. Private equity är den investeringsform som inom samlingsbegreppet risThe risk capital market can be traced as far back as the 1940s when the first private equity investment was made in the United States, and since then, the industry has constantly changed along with the current economic climate, and is today a strongly established phenomenon even in Sweden. The term private equity covers all investments that are made in unlisted companies and they typically involv

When China opened it borders in 1979, the country suffered from a severe brain drain as its most talented students left the country to take advantage of educational opportunities abroad. However these emigrant engineers, known locally as "sea turtles" or Chinese returnees, have become a valuable asset for Zhongguancun Science Park. The authorities for the high-tech park are now adopting

The European integration is one of the spectacular historical events. The result that has been obtained would be virtually impossible for any other regional organization to achieve. However, the continuation of this accomplishment depends upon some premises. Throughout this study, the crucial dynamics of the last two decades, which have rekindled the integration endeavor, are questioned from the n

The Naqshbandi-Haqqani Sufi order has spread throughout the world extensively since it was founded in 1973 by its Sheikh Muhammad Nazim Adil al-Haqqani. The present thesis analyses one local branch of that order in Eastern London within a theoretical framework of New Social Movements, as formulated by the Italian sociologist Alberto Melucci. A general picture of Muslim presence in Britain is given
